Practical Aspects of Emulsions for the Pharmaceutical, Cosmetic and Related Industries

Ricardo Diez, Ph.D.

Course description

While it is common knowledge that water and oil do not mix, it is less known that given the right chemistry and processing, a cosmetically elegant emulsion of these two immiscible liquids can be made stable for years. But without proper knowledge of the science behind emulsions, failures can occur.

This accredited training course is designed to provide both theoretical understanding and practical application of the complex behavior of emulsions. The course uses a unique approach based on combining the different but totally related learnings of parts 1 and 2.

Part 1 is dedicated to studying in depth the physical chemistry of the key raw materials used to make emulsions. The materials are divided in the categories of emollients, emulsifiers and structuring agents.

Part 2 will apply the acquired knowledge to the understanding and learning of the various technologies obtained by the synergistic physical interactions of the raw materials. The Lamellar Gel Network Model (LGNM) is described in detail with emphasis in its practical application to controlling the sensorial properties of emulsions, its stability and scale up during the manufacturing process. Formulation examples are used to illustrate the application of the technologies.

There is a specific section dedicated to the delivery of actives, and its release from the emulsions. Specific cases of non-delivery through the skin, such as sunscreen actives, are also addressed.

Upon completion of this course, you will be able to:

• Describe the physical chemistry characteristics of the key materials used to make emulsions
• Explain the physical interactions of those materials in the creation of the multiphases that form the internal structure of emulsions
• Define the Lamellar Gel Network Model and its application to controlling the sensorial properties and stability of emulsions, as well as the delivery of actives
• Describe the details of the scale‐up operation from lab samples to plant batches
• List ten model emulsion prototypes that cover a wide range of properties, as well as a review of commercial products
